The popular Swedish reality television series 'Married at First Sight' is set to return for its thirteenth season, with the autumn edition titled 'Married at First Sight - In Winter Attire' premiering on October 2nd on SVT. This marks the second time the program will air during the fall season, expanding the show's traditional broadcast schedule and offering viewers additional content beyond the usual spring installment.

A significant development for this season is the introduction of psychologist Katarina Blom as one of the four relationship experts who will guide participants through their marital journeys. Blom joins the existing panel of specialists, bringing fresh psychological perspectives to the matchmaking process. In a press release, she expressed her hope to make psychology and therapy more accessible and useful in both viewers' and participants' daily lives, emphasizing psychology as a powerful tool for personal transformation.

The season features eight singles who will marry complete strangers at first sight, with the cast consisting of five men and three women forming four couples. The participants come from various professional backgrounds and locations across Sweden, including Malin Strömbäck, a 34-year-old treatment pedagogue from Norrköping; Patrik Stovell, a 38-year-old gym owner from Kungsbacka; and Tobias Branning, a 35-year-old customer service group manager from Helsingborg.

Other contestants include Abtin Jahani, a 36-year-old radiologic nurse from Gothenburg; Jimmy Erlandsson, a 40-year-old border trade regional manager from Strömstad; and Hanna Bergenholtz, a 32-year-old home care coordinator from Halmstad. The expert panel supporting these couples through their unconventional marital beginnings also includes matchmaking expert Lemarc Thomas making a comeback, alongside psychologist Fredric Bohm and Suzann Larsdotter, a specialist in clinical sexology.

Attached to nearly every human cell is an antenna-like structure known as the primary cilium, which senses the cell's environment and controls how it responds to signals from its surroundings. New research from the U.S. and Sweden has mapped and identified hundreds of proteins that comprise these structures, contributing new insights for future research into ciliary biology, disease mechanisms and potential therapies.

Publishing in the journal Cell, researchers from KTH Royal Institute of Technology and Stanford University used advanced imaging and antibody-based techniques to map proteins inside primary cilia across three types of human cells. They analyzed more than 128,000 individual cilia and identified 715 proteins that are located in different parts of the cilium responsible for sensing mechanical or chemical signals, such as hormones. These primary cilia are distinct from motile cilia, which are responsible for movement of fluids or cells.

Professor Emma Lundberg, a researcher in cellular and clinical proteomics at KTH Royal Institute of Technology, says the study also identified a possible gene behind various disorders linked to malfunctions of the cilium. These can lead to disorders affecting many parts of the body, from the brain and eyes to the kidneys and bones. In addition, the researchers discovered 91 proteins that had never before been linked to cilia.

The study expands the current understanding of cilia, casting them as highly adaptable and versatile processors of information, which tune their protein composition to suit the needs of the cell they belong to. "Cells seem to customize the protein composition of their cilia to have them perform specific sensing tasks," Lundberg says. "These newly-discovered ciliary proteins inspire many new hypotheses about their roles in cellular function and human health."
